85445 Heinz bodies induced
Also known as: Heinz bodies induced, unstable hemoglobin test
Visualization of Heinz bodies in red blood cells after chemical induction with oxidative reagent (typically methylene blue or brilliant cresyl blue) to precipitate unstable hemoglobin.
In Plain Language
induced hemoglobin crystal test; red cell oxidative stress test
Clinical Context
Detects unstable hemoglobins and glucose-6-phosphate dehydrogenase deficiency; more sensitive than direct Heinz bodies for identifying oxidative hemoglobinopathy.
